Amazon.com, Inc & Ors v Interdigital VC Holdings, Inc & Ors

Amazon.com, Inc & Ors v Interdigital VC Holdings, Inc & Ors

There is a strong and sufficient likelihood that InterDigital would seek anti-suit relief to restrain Amazon's pursuit of final RAND relief in the UK if not prevented by the AASI. The AASI Order is justified to protect the UK court's jurisdiction and prevent vexation or oppression. The Order does not offend comity, as it does not restrain InterDigital from pursuing substantive patent infringement claims or contesting the effect of any UK-determined licence in foreign courts. Clarifications to the Order are appropriate to confirm its scope but do not alter its material effect.
